- This provides visual interest and reminds the user to be conscious of the time that the user is brushing or rinsing.
- the hourglass shape may provide a timing function. More particularly, the user may brush or rinse until all of the composition 412 has flowed from the first (e.g., upper) portion 420 to the second (e.g., lower) portion 430 .

Abstract
Description
- Compositions are typically stored in a dispenser. For example, toothpaste may be stored in a tube that is squeezed to eject the toothpaste therefrom. In another example, a shampoo may be stored in a bottle, and the shampoo may be poured out of the bottle. The composition may have a tendency to separate into portions of higher and lower densities in conventional dispensers. In addition, conventional dispensers do not appeal to children, and thus, provide no incentive for the children to use the composition. What is needed is an improved dispenser.
- A dispenser includes a spiral-shaped body having a first end and a second end. The body defines an internal volume and an opening that provides a path of fluid communication between the internal volume and an exterior of the body. A composition is in the internal volume.
- In another embodiment, the dispenser includes a body having a first portion, a second portion, and a neck portion. The first portion defines a first internal volume, and the second portion defines a second internal volume. The neck portion is positioned between the first and second portions and provides a path of fluid communication between the first and second internal volumes. A minimum cross-sectional width of the neck portion is less than about 20% of a maximum cross-sectional width of the first portion, the second portion, or both. A composition is in the first internal volume, the second internal volume, or both.
- A method for dispensing a composition from a dispenser is also disclosed. The method includes rotating a spiral-shaped body about a longitudinal axis. The body includes a curved central axis that extends from a first end to a second end, and the longitudinal axis is perpendicular to a plane that includes the central axis. A lid that is coupled to the body is opened to allow the composition to flow out of the body.

FIGS. 1 and 2 depict a perspective view and a cross-sectional side view, respectively, of a spiral-shaped dispenser 100, according to an embodiment. Thedispenser 100 may include abody 110. Thebody 110 may be made of a polymer or elastomer. For example, thebody 110 may be made of a blow-molded polyethylene terephthalate (“PET”). Thebody 110 may define an internal volume. Acomposition 112 may be stored in the internal volume. Thecomposition 112 may be or include a dentifrice composition (e.g., toothpaste, tooth powder, tooth soap, mouthwash). In other embodiments, thecomposition 112 may be or include personal care or home care compositions such as lotions, soap, shampoo, conditioner, dish detergent, laundry detergent, fabric softener, surface cleaners, etc. In at least one embodiment, thebody 110 may be at least partially transparent or translucent so that the user may see thecomposition 112 in the internal volume. - The
body 110 may be substantially spiral-shaped. As shown, thebody 110 may include a first (e.g., “inner”)end 114 and a second (e.g., “outer”)end 116. Thebody 110 may include a curved, spiralcentral axis 118 that extends from thefirst end 114 to thesecond end 116. Thecentral axis 118 may extend around thefirst end 114 from about 180° to about 270°, about 270° to about 360°, about 360° to about 450°, about 450° to about 540°, about 540° to about 630°, about 630° to about 720°, or more. In the embodiment shown, thecentral axis 118 extends through about 630°. As shown, thebody 110 may be in the shape of a two-dimensional spiral, where thecentral axis 118 is in a plane. In another embodiment, thebody 110 may be in the shape of a three-dimensional spiral, where thecentral axis 118 is in the shape of a helix. - A
radial distance 120 between thefirst end 114 and thecentral axis 118 may increase proceeding along thecentral axis 118 away from thefirst end 114. A cross-sectional shape of thebody 110, in a plane perpendicular to thecentral axis 118 may be substantially circular, ovular, rectangular, or the like. A cross-sectional area through thebody 110, in the plane perpendicular to thecentral axis 118, may increase proceeding away from thefirst end 114 to a portion of maximumcross-sectional area 122. The cross-sectional area through thebody 110 may then decrease proceeding away from the portion of maximumcross-sectional area 122 toward thesecond end 116. Although not shown in the Figures, in another embodiment, the cross-sectional area may remain substantially constant proceeding from thefirst end 114 to thesecond end 116. Although not shown, in another embodiment, the cross-sectional area may increase (with no decrease) proceeding from thefirst end 114 to thesecond end 116. Although not shown, in another embodiment, the cross-sectional area may decrease (with no increase) proceeding from thefirst end 114 to thesecond end 116. - The
body 110 may define an opening 124 (seeFIG. 2 ) that provides a path of fluid communication between the internal volume and an exterior of thebody 110. The opening 124 may be positioned between the first andsecond ends 114 of thebody 116. As shown, the opening 124 may be positioned on an outer radial surface of thebody 110. In another embodiment, the opening 124 may be positioned on a side surface of the body 110 (e.g., rotated 90° from the outer radial surface with respect to the central axis 118). In yet another embodiment, theopening 124 may be positioned proximate to (e.g., through) thesecond end 116 of thebody 110. - A
lid 130 may be coupled to thebody 110. Thelid 130 may be aligned with and/or covering theopening 124. Thelid 130 may be coupled to thebody 110 using a threaded engagement, a snap-fit engagement, adhesive, or the like. -
FIG. 3 depicts a perspective view of thedispenser 100 on its side showing thelid 130 in an open position, according to an embodiment. Thelid 130 may include abase 132 and acap 134. The base 132 may be coupled to thebody 110 of thedispenser 100. The base 132 may have an opening (e.g., a nozzle) 136 formed therethrough. - The
cap 134 may be coupled to thebase 132 by one or more hinges. In another embodiment, thecap 134 may screw or snap onto thebase 132. Thecap 134 is shown in a closed position inFIGS. 1 and 2 . Thecap 134 may prevent thecomposition 112 from flowing through theopenings cap 134 is in the closed position. Thecap 134 may pivot or rotate about the hinge(s) into an open position, as shown inFIG. 3 . Thecomposition 112 may flow through theopenings cap 134 is in the open position. - Referring again to
FIGS. 1 and 2 , the outer surface of thecap 134 may be substantially flat. As a result, when thelid 130 is in the closed position, the outer surface of thecap 134 may rest upon a horizontal external surface (e.g., of a table or a counter top), and thelid 130 may be positioned between thebody 110 and the external surface to hold the dispenser in an “upright” position as shown inFIG. 2 . A plane through thecentral axis 118 may be substantially perpendicular to the external surface. When thedispenser 100 is in this position (i.e., the “upright” position), theopening 124 in thebody 110 may be the lowest (or close to the lowest) point on thebody 110, such that gravity may cause thecomposition 112 to aggregate near theopening 124. This may allow a user to quickly dispense thecomposition 112 from thedispenser 100. - Due to the curvature of the
body 110, at least a portion of thecomposition 112 in the internal volume may not be able to flow to theopening 124 in thebody 110 when thebody 110 is in the upright position because the path to theopening 124 may be at least partially upward. For example, the portion of thecomposition 112 between thefirst end 114 and the dashedline 140 may not be able to flow to theopening 124 in thebody 110 when thebody 110 is in the upright position. Similarly, the portion of thecomposition 112 between the dashedline 140 and thesecond end 116 may not be able to flow to theopening 124 in thebody 110 when thebody 110 is in the upright position. As a result, to cause these portions of thecomposition 112 to flow to theopening 124, the user must rotate thebody 110 clockwise or counterclockwise about an axis through thefirst end 114 that is perpendicular to a plane containing thecentral axis 118. - An inner surface of the
body 110 that defines the internal volume may include acoating 150 disposed thereon (seeFIG. 2 ). A coefficient of friction between thecomposition 112 and thecoating 150 may be less than a coefficient of friction between thecomposition 112 and an inner surface of thebody 110. Thecoating 150 may prevent thecomposition 112 from sticking to the inner surface of thebody 110, thereby allowing thecomposition 112 to slide or slosh or otherwise move around within the internal volume of thebody 110 when the user rotates thedispenser 100. In at least one embodiment, thecoating 150 may be or include a liquid-impregnated surface, as described in U.S. Pat. No. 8,940,361. For example, thecoating 150 may include a matrix of solid features spaced sufficiently close to stably contain a liquid therebetween or therewithin. In at least one embodiment, thecoating 150 may be or include LiquiGlide® manufactured by LiquiGlide Inc. of Cambridge, Mass. - Rotating the
dispenser 100 may serve to mix thecomposition 112 within the internal volume of thebody 110 to help the composition remain substantially uniform over time, rather than potentially separating into a higher density portion and a lower density portion. Furthermore, the shape of thedispenser 100 may amuse, entertain, or appeal to young children, which may encourage them to use the composition 112 (e.g., to brush their teeth). - In operation, a user may grasp the
dispenser 110 and open thelid 130. Thecomposition 112 may flow out through theopening 124 in thebody 110 and theopening 136 in thelid 130 due to gravity. The user may also squeeze thebody 110 to cause thecomposition 112 to flow out through theopening 124 in thebody 110 and theopening 136 in thelid 130. When the level ofcomposition 112 in the internal volume is low, the user may have to rotate thebody 110 to cause some of thecomposition 112 to flow toward theopenings composition 112 has flowed out of thebody 110, the user may close thelid 130, and place thedispenser 100 on a substantially horizontal surface in its upright position. -
FIGS. 4 and 5 depict a perspective view and a cross-sectional side view, respectively, of an hourglass-shapeddispenser 400, according to an embodiment. Thedispenser 400 may include abody 410. Thebody 410 may be made of a polymer or elastomer. For example, thebody 410 may be made of a blow-molded polyethylene terephthalate (“PET”). Thebody 410 may define an internal volume. Acomposition 412 may be stored in the internal volume. Thecomposition 412 may be or include a dentifrice composition (e.g., toothpaste, tooth powder, tooth soap, mouthwash). In other embodiments, thecomposition 412 may be or include personal care or home care compositions such as lotions, soap, shampoo, conditioner, dish detergent, laundry detergent, fabric softener, surface cleaners, etc. In at least one embodiment, thebody 410 may be at least partially transparent or translucent so that the user may see thecomposition 412 in the internal volume. - The
body 410 may be substantially hourglass-shaped with a centrallongitudinal axis 414 extending therethrough. As shown, thebody 410 may include a first (e.g., “upper”)portion 420 and a second (e.g., “lower”)portion 430, although the terms “upper” and “lower” are relative because thebody 410 may be flipped. Thefirst portion 420 of thebody 410 may include a first portion of the internal volume, and thesecond portion 430 of thebody 410 may include a second portion of the internal volume. An axial end of thefirst portion 420 may include a flatouter surface 424, and an axial end of thesecond portion 430 may include a flatouter surface 434, such that thebody 410 may be in an upright position when resting on either one of thesurfaces body 410 may also include anarrow neck portion 440 positioned between the first andsecond portions neck portion 440 may provide a path of fluid communication between the first and second portions of the internal volume. - When a cross-section is taken through the
body 410 in a plane that is perpendicular to the centrallongitudinal axis 414, the cross-sectional shape of thebody 410 may be substantially circular at any height along the centrallongitudinal axis 414. The cross-sectional width of thefirst portion 420 of thebody 410 may decrease proceeding from a maximumcross-sectional width 422 toward theneck portion 440. The cross-sectional width may then increase again proceeding from theneck portion 440 toward a maximumcross-sectional width 432 of thesecond portion 430 of thebody 410. A minimumcross-sectional width 442 of theneck portion 440 may be less than about 50%, less than about 25%, or less than about 10% of the maximumcross-sectional width 422 of thefirst portion 420, the maximumcross-sectional width 432 of thefirst portion 430, or both. - The minimum
cross-sectional width 442 of theneck portion 440 may be from about 10 mm to about 20 mm or from about 20 mm to about 30 mm. The minimumcross-sectional width 442 may be dependent on the viscosity of thecomposition 412, the coating 470 (introduced below) on the inner surface of the body 410), or a combination thereof. Thecross-sectional width 442 of theneck portion 440 may be less than thecross-sectional widths second portions composition 412 moving from thefirst portion 420 to thesecond portion 430, creating an hourglass-like movement, where thecomposition 412 pools up and then slowly flows in the second (e.g., lower)portion 430. This provides visual interest and reminds the user to be conscious of the time that the user is brushing or rinsing. The hourglass shape may provide a timing function. More particularly, the user may brush or rinse until all of thecomposition 412 has flowed from the first (e.g., upper)portion 420 to the second (e.g., lower)portion 430. However, the time may decrease as the amount ofcomposition 412 decreases. - The
body 410 may define an opening 450 (shown inFIG. 5 , but not shown under thelid 460 inFIG. 4 ) that provides a path of fluid communication between the internal volume and an exterior of thebody 410. Theopening 450 may be positioned proximate to an axial end of thefirst portion 420 of thebody 410 or thesecond portion 430 of thebody 410. Although not shown, in another embodiment, theopening 450 may be formed on/through theneck portion 440 of thebody 410. - A
lid 460 may be coupled to thebody 410 and be aligned with and/or cover theopening 450. Thelid 460 may be coupled to thebody 410 using a threaded engagement, a snap-fit engagement, adhesive, or the like. In at least one embodiment, thelid 460 may be substantially flush with the outer surface of thebody 410, as shown inFIG. 4 . - The user may flip/rotate the body 180° (e.g., like an hourglass) to cause the
composition 412 to flow from one portion of the body 410 (e.g., the first portion 420), through theneck portion 440, and into the other portion of the body 410 (e.g., the second portion 430), and vice versa. Flipping/rotating thebody 410 may serve to mix thecomposition 412 within the internal volume of thebody 410 to help thecomposition 412 remain substantially uniform over time, rather than potentially separating into a higher density portion and a lower density portion. Furthermore, watching thecomposition 412 flow like sand in an hourglass may amuse, entertain, or appeal to young children, which may encourage them to use the composition 412 (e.g., to brush their teeth). - An inner surface of the
body 410 that defines the internal volume may include acoating 470 disposed thereon (seeFIG. 5 ). A coefficient of friction between thecomposition 412 and thecoating 470 may be less than a coefficient of friction between thecomposition 412 and an inner surface of thebody 410. Thecoating 470 may prevent thecomposition 412 from sticking to the inner surface of thebody 410, thereby allowing thecomposition 412 to slide or slosh or otherwise move around within the internal volume of thebody 410 when the user flips/rotates thedispenser 400. In at least one embodiment, thecoating 470 may be or include LiquiGlide®. - In operation, a user may grasp the
dispenser 410 and open thelid 460. The user may then flip/rotate thedispenser 410 180° so that thecomposition 412 may flow out through theopening 450 in thebody 410 due to gravity. The user may also squeeze thebody 410 to cause thecomposition 412 to flow out through theopening 450 in thebody 410. After thecomposition 412 has flowed out of thebody 410, the user may flip/rotate thedispenser 410 180° again so that thebody 410 is upright (e.g., as shown inFIG. 5 ), and the user may close thelid 460. -
FIGS. 6 and 7 depict a front view and a cross-sectional view, respectively, of another hourglass-shapeddispenser 600, according to an embodiment. In contrast to the upper andlower portions dispenser 400 shown inFIGS. 4 and 5 that are at least partially substantially spherical or spheroid-shaped, the upper andlower portions dispenser 600 shown inFIGS. 6 and 7 are at least partially substantially frustoconical. In addition, the upper andlower portions dispenser 600 are slimmer than the upper andlower portions dispenser 400. - The
dispenser 600 may include thecomposition 612 therein and have thecoating 670 on the interior of thebody 610 that allows, facilitates, or reduces the resistance of thecomposition 612 to moving around within thebody 610 with minimal friction. -
FIG. 8 depicts a flowchart of amethod 800 for dispensing a composition from adispenser method 800 may include rotating abody body 110 may be rotated from about 45° to about 90°, about 90° to about 180°, or more. In one embodiment, this may include rotating a spiral-shapedbody 110 about a longitudinal axis that is perpendicular to a plane that includes a curvedcentral axis 118 through thebody 110. In another embodiment, this may include rotating an hourglass-shapeddispenser upper portion lower portion - The
